I'm not overly familiar with ISA, but we've had it for a while now and it seems to do a job and there doesn't seem to be an immediate need to swap it out, but i just can't work out how to do this!
We have site A connected via Cisco VPN in the 192.168.202.x range. Our LAN (site B) is 192.168.1.x and the VPN terminates on 192.168.1.10. The default gateway (the ISA server) of site B is 192.168.1.254. If i want a computer on site B wants to talk to Site A, i add a persistent route on the computer to tell it to use 192.168.1.10 as the gateway and all is well.
I now have a scenario where an IP device on site A needs to connect to site B but doesn't have the facility to let me add another static route. Can i tell ISA to forward any requests for 192.168.202.x that is receives to 192.168.1.10? That would potentially mean i dont have to add any more routes
